There's a post on LinkedIn with a picture of a sign they put on one of their misbehaving sympaChargers. Not sure if it's the one here or a different one. Surprisingly, the sign lists 2 alternate charging stations, both seem to be by MOVE, instead of more sympaChargers.
But there's supposed to also be a second sympaCharger in Walenstadt, a temporary unit somewhere near Kronenweg according to their website https://www.sympacharge.com/der-sympacharger.html
